CAPS ULE-STRIPPING DEVICE.

SPECIFICATION forming part of Letters Patent No. 323,159, dated July 28, 1885.

Application filed March 26, 1884. (No model.)

To all whom it may concern:

Be it known that I, JOHN KREHBIEL, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Devices for Stripping Capsules from the Mold-Pins; and I declare that the following is a full, clear, and exact description thereof.

This invention relates to certain new and useful improvements in the construction and operation of a device to be operated by hand for withdrawing gelatine capsules from the moldpins upon which such capsules are formed. Such capsules are formed by dipping a series of metallic mold-pins, which are arranged upon a plate in regular series, into a vessel containing gelatine at a suitable degree of heat and then withdrawing them, when a thin film of gelatine will be found upon such mold-pins. Upon being sufficiently cooled or set it is necessary by some process to cut the capsules into equal and desired lengths upon the pins, after which the capsules must be withdrawn from said pins in such a manner as not to injure them.

The object of this invention is to provide a tool by which this can be accomplished rapidly and with entire safety, while the tool is so constructed that it can be easily repaired and kept in order.

Figure 1 is a perspective view of one section of my improved tool, there being as many different sections as there are rows'or series of mold-pins upon the plate, and each section being like its fellow. Fig. 2 is a top plan view of the frame with all its sections in place, and showing the manner of operation. Fig. 3is a sectionaldetail showing one of the four screws, all these screws being alike.

In the accompanying drawings, which form a part of this specification, A represents a block, the two sides of which tumble in, so that the lower face of this block is narrower than its top face. To each side of this block,

and in pairs immediately opposite each other, are secured by the screws a the spring-plates B, thelower ends of which turn inward in L shape, as shown at b, and the approaching edges of these L-shaped feet are each cutaway in halfround, as shown at c, to wholly or in part embrace the capsule-mold pin (1.

A clamp or plate, 0, is securely fastened to the inner face of each of the spring-plates, adapted to hold in place by its lower end the rubber block D, the lower end of which rests upon the rear edge of the jaw-plate E, one pair of these jaw-plates being provided for each pair of spring-plates, their front edges being coincidently cut out half-round to embrace the mold-pin. These jaw-plates may be hinged at their rear edges to the spring-plates, near the feet thereof, and they are so arranged that each pair of jaw-plates will, when not in use, lie flat upon the feet of the spring-plates, the circular hole formed by the cut-away portions on their adjacent edges being preferably a little less in diameter than that of the mold-pin when covered with the gelatine film. Instead of hinging such plates as above described,I prefer to cut or form a lip on the center of the rear edge of each of the jaw-plates, adapted to enter a slot, e, cut or formed at the point of conjunction between the spring-plate and the heel thereof. I deem thislatter the preferable way, because of the greater facility it affords for repairing and keeping in order these jawplates as they become worn in use.

Each pair of spring-plates, with its attachments,as hereinbeforedescribed, forms a section complete in itself, and as many of these sections are secured to the block as there are mold-pins in the row or series. As many blocks are secured in the frame as there are rows or series of mold-pins running in the opposite direction, it being understood that such mold-pins project from the face of a circular plate in rows, so that each four of such pins stand at a corner of a square.

F is a circular frame,in which are removably secured the blocks A, each one being constructed and provided with the attachments already described. At equal distances apart, and near the periphery of this frame, it is pierced with a threaded hole to receive and engage with the screw G, there being four of foot, f, so arranged that when the device is in use these feet will rest upon the capsule-mold plate being operated upon for the time being.

In practice the frame carrying the sections is placed over the mold-plate so that each mold-pin projecting therefrom will enter its proper place through the cutaway portion of the feet of the spring-plates, the top of such mold-pin striking the jaw-plates and forcing their inner edges upward until the pin will pass upward as far as is desired. These jawplates are prevented from opening too far by the pressure of the rubber blocks, which also have a tendency, when the direction of the motion of the pin is reversed, to compel the jaw-plates to tightly embrace such mold-pin. Now, the cranks attached to the heads of the screws being moved in the right direction, the device is gradually withdrawn from the moldpins, the jaw-plates closing upon said pins and forcing the capsules from them.

Should the jaw-plates become worn by use, the set-screws a are employed to force the spring plates closer together, so that such wear is compensated for.

hat I claim as my invention is 1. The combination, with a capsule moldpin, of a pair of jaws having their adjacent edges cut away to partially embrace said mold-pin, and an independent separate support for each jaw, substantially as and for'the purpose specified.

2. The combination, with a capsule moldpin, of a pair of movable jaws and independent supports for the same, said jaws having their adjacent edges cut away to partially embrace said mold-pin, and their opposite edges bearing against said independent support, and the latter provided with stops to limit the motion of the jaws in one direction, substantially as described.

3. In a device for the purpose described, the combination of the block A, spring-plates B,secured to said block and arranged in opposite pairs, and provided with feet I), and the separate and independent jaw-plates E, supported by said spring-plates, substantially as specified.

4. In a device for the purposes described, the combination of the blocks A, spring-plates B,secured to the sides thereof, clamp-plates O, secured to the inner sides of said spring-plates, rubber blocks D,and jaw-plates E, supported by said spring-plates, the parts being constructed and operating substantially as set forth.

5. In a device for the purpose described, the combination of the blocks A in series, and provided with the spring and jaw plates and their attachments, herein described, with the frame F, provided with screws G, and means, substantially as described, for giving said screws a simultaneous movement in either direction, substantially as and for the purposes set forth.
